Bottom Detection
Locating the bottom is important for the ES80. The purpose of the
parameters are to define the upper and lower depth limits most likely to be used
during the ES80 operation. You can also modify the setting for
change the bottom detection relative to the bottom echo.

Colour Scale
The colour scales used by the ES80 are designed to reflect the how strong the
echoes are. The echo strength is measured in decibels (dB). In the basic colour
scale with 12 colours, each colour represents a 3 dB step. This means that the
entire scale covers 36 dB. The dynamic range of the ES80 is much larger. The
parameters allow you to change the lower limit of colour scale range
